The Orca

The Orca is a copper and silver ionisation system for the control of Legionella, Pseudomonas and other disease causing bacteria in water systems.There are three different Orca models to choose from and the model specified will be dependant upon the use case, the sites water consumption and a site survey carried out by a qualified ProEconomy engineer.

KB1

The KB1 is our leading model that can treat up to 100 litres per minute. It utilises our latest touchscreen technology and is compatible with our latest self-adjusting pods. It also has data-downloading functionality and so can be used with Tetras.

KB2

The KB2 is our medium-sized model. It runs from 100 - 250 litres per minute and uses a 6-pod manifold made up of 5 coper pods and 1 silver pod. It also comes with our latest touchscreen displays and is designed to work with our self-adjusting pods. Data downloading functionality is built into the system, as is descaling software and Modbus BMS.

KB3

The KB3 is our largest unit. Being modular, it can come with any configuration of 6-pod manifolds to match the water flow rate. We have, for example, KB3s that run at 300 litres per minute using only two 6-pod manifolds, but have fitted systems that cope easily with 700 litres per minute.

Tetras

Tetras is ProEconomy's cloud-based water management system that is simplifying the way you manage your water risk.

One of our City and Guilds accredited samplers will sample your site's water and add the sample results to an easy to use, accessible cloud based water system free of charge. Here you can trend sample results over time, view pod transactions, create custom alerts and analyse individual sample results. There's even the option to download your results into Excel spreadsheets, while our client relations team are on-hand to answer any queries.

In this way, Tetras gives you full, transparent access to your individual sample details and site-wide results so any water issues are detected and treated before contamination occurs

A 4-Step Approach (Adapted from Stout and Yu, 2003)

Peer-reviewed and published reports of controlled studies of prolonged duration of efficacy in controlling Legionella growth and preventing cases of hospital-acquired Legionnaires’ disease in individual hospitals.

Chemical Water Treatment Methods

Although a popular method of Legionella control, chemical water treatment can cause health hazards to humans and the environment. Unlike other chemical water treatment methods, copper silver ionisation has no COSHH issues and is safe to use.

You can find out more about the different chemical water treatment methods below. Alternatively, contact our team if you have any questions.

Temperature Control

Temperature control has been the method traditionally applied to control Legionella in water systems. It entails having to obtain 55°C and above after running any hot water tap for 1 minute, and 20°C and below after running any cold water tap for 2 minutes (DH HTM04-01 2016).

Unfortunately, pathogens in biofilms are protected as penetration by temperature is limited. This may cause pieces of the top layers of biofilm to break loose under the action of shear forces from the water. These can then settle elsewhere in the water system (Center for Biofilm Engineering). Furthermore, mixing valves are often used to avoid the risk of scalding. These valves will mix the water to a temperature at which pathogens grow most rapidly, and their inner components often include materials that encourage biofilm formation (DH HTM04-01, 2016).

In fact, only 13% of the results of tests carried out by the UK Building Services Research and Information Association (BSRIA) in 1996 using temperature control were free of Legionella.

Ultra Violet light (UV) and Ozone (O3)

Ultra Violet light (UV) and Ozone (O3), according to HSE HSG274 and HTM04-01, are not intended to be dispersive. Instead, they are designed to have their effect only at or very close to the point of application. Therefore, removing biofilm in water systems is difficult, if not impossible.
